A shot blasting equipment and process for roughening and anti-slip treatment of stone surfaces

Abstract

This invention discloses a shot blasting equipment and process for roughening and anti-slip treatment of stone surfaces. Applied to the field of stone roughening and anti-slip treatment technology, this invention incorporates a lifting component. When the roughened stone passes through the lifting component, it pushes the component upwards, causing the roller and air-blowing component to rise along the guide bracket. This allows the brush and air-blowing component to adapt to the height of the stone, providing flexibility for shot removal and dust removal. Furthermore, the stone's transport causes the lifting component to rotate, periodically striking the stone. This vibration loosens the broken shot and dust adhering to the stone, improving the subsequent cleaning effect of the brush. The combined use of the air-blowing component and brush allows the brush to pre-clean the shot and dust from the stone, while the adjustable-angle air-blowing component blows the shot and dust away from the stone's surface.

Description

Technical Field

[0001] This invention belongs to the field of stone roughening and anti-slip treatment technology, and specifically relates to a shot blasting equipment and process for roughening and anti-slip treatment of stone surfaces. Background Technology

[0002] To enhance the aesthetic appeal of marble, granite, and other natural stones, surface roughening treatment is necessary. This process creates a surface with a certain degree of roughness. Generally, shot blasting is used to roughen the stone's surface. The powerful, dense shot blasts from the shot blaster strike the stone's surface, causing the outer layer to peel off and creating the desired roughness.

[0003] Currently, after roughening the stone, shot blasting equipment on the market often leaves shot and dust accumulating on the stone surface. If the roughened stone is directly transported out, some shot cannot be recycled and it is easy to pollute the surrounding environment. Furthermore, when the shot is thrown at high speed and hits the stone surface, it will break due to the impact force and some of the broken shot will adhere to the stone, thus affecting the subsequent stone processing work.

[0004] Based on the above-mentioned issues, it can be found that existing devices on the market are difficult to avoid the problems mentioned above when in use. Moreover, even if they can be solved, the simple brush structure cannot achieve the desired effect. Therefore, we propose a shot blasting device for roughening and anti-slip treatment of stone surfaces, which can remove broken shot and dust adhering to the stone, reduce environmental pollution, and ensure the recycling of intact shot. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing shot blasting equipment for roughening and anti-slip treatment of stone surfaces. Its advantages include the use of a lifting component. When the roughened stone passes through the lifting component, it pushes the component upwards, causing the roller and air-blowing component to rise along the guide bracket. This allows the brush and air-blowing component to adapt to the height of the stone, providing flexibility in shot removal and dust removal. Furthermore, the stone's transport drives the lifting component to rotate, periodically tapping the stone. This vibration loosens the broken shot and dust adhering to the stone, improving the subsequent cleaning effect of the brush. The combined use of the air-blowing component and brush allows the brush to pre-clean the shot and dust from the stone, while the adjustable-angle air-blowing component blows the shot and dust away from the stone's surface. The shot and dust then pass through a mesh belt conveyor structure and fall into a spiral shot collection structure, thus recovering residual shot and preventing dust pollution.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a shot blasting device for roughening and anti-slip treatment of stone surface, comprising a mesh belt conveyor structure, a shot blasting chamber bolted to the top of the mesh belt conveyor structure, two shot blasters bolted to the top of the shot blasting chamber, a separation structure bolted to the bottom of the mesh belt conveyor structure, a lifting structure provided on the rear side of the separation structure, a storage bin provided on the top of the front side of the lifting structure, and the storage bin communicating with the shot blasters, a spiral shot collecting structure bolted to the left side of the bottom of the mesh belt conveyor structure, and the spiral shot collecting structure communicating with the separation structure, and a shot removal structure provided on the left side inside the shot blasting chamber, and the shot removal structure working in conjunction with the mesh belt conveyor structure;

[0007] The shot removal structure includes two guide brackets, which are bolted to the left side of the shot blasting chamber. Mounting brackets are bolted to both sides of the opposite side of the two guide brackets. A blower assembly is installed inside the left mounting bracket, and a lifting assembly is bolted to the bottom of the right mounting bracket. A roller is rotatably connected between the opposite sides of the two guide brackets, and the surface of the roller is provided with several bristles in a ring shape.

[0008] By adopting the above technical solution, a lifting component is set up. When the roughened stone passes through the lifting component, the stone pushes the lifting component to rise, which in turn lifts the roller and the air blowing component along the guide bracket. This allows the brush bristles and air blowing component to adapt to the height of the stone, thus providing flexibility for shot removal and dust removal. The conveying of the stone drives the lifting component to rotate, causing the lifting component to periodically tap the stone. This vibration loosens the broken shot and dust adhering to the stone, thereby improving the cleaning effect of the brush bristles on the shot and dust. Through the combined use of the air blowing component and brush bristles, the brush bristles pre-sweep the shot and dust on the stone, and then the air blowing component with an adjustable blowing angle blows the shot and dust off the upper surface of the stone. The shot and dust fall into the spiral shot collection structure through the mesh belt conveyor structure, thus playing a role in recovering residual shot and preventing dust pollution.

[0009] The present invention is further configured such that: the lifting assembly includes two fixed support plates, and the fixed support plates are disposed at the bottom of the right mounting bracket, and a rotating roller is rotatably connected between the opposite sides of the two fixed support plates; the surface of the rotating roller is annularly welded with a paddle plate; a rotating shaft is bolted to both the front and rear sides of the rotating roller, and the side of the rotating shaft near the fixed plate passes through the interior of the fixed plate and is connected to a striking component; an arc-shaped elastic sheet is welded to the top of both the fixed support plate and the striking component, and the top of the arc-shaped elastic sheet is welded to the right mounting bracket.

[0010] By adopting the above technical solution, when the stone moves to the position of the paddle, it will push the paddle and the roller to rotate, so that the other paddles arranged around the roller will contact the upper surface of the stone, thereby raising the overall height of the roller. In turn, the mounting bracket will raise the height of the roller and the air blowing component. Furthermore, by utilizing the elasticity of the arc-shaped elastic sheet, the paddle can adapt to the surface curvature of the stone, ensuring good contact between the paddle and the stone. As the stone pushes the roller to rotate, it will drive the striking component to move through the rotating shaft, causing the striking component to periodically hammer the stone, thereby vibrating the stone. This will loosen the broken pellets and dust attached to the stone surface, thereby improving the cleaning effect of the subsequent brush bristles and air blowing component.

[0011] The invention is further configured such that: the striking component includes a connecting support plate; the rotating shaft extends to the outside of the connecting support plate from the side near the connecting support plate, and a cam is sleeved on the surface of the rotating shaft; fixed plates are welded to the top and bottom of the right side of the connecting support plate; a connecting plate is welded between the opposite sides of the two fixed plates; movable plates are rotatably connected to the opposite sides of the two connecting plates on the front and rear sides; a striking rod is welded to the right side of the bottom of the movable plate; a pressure spring is provided between the movable plate and the top fixed plate; and the movable plate is used in conjunction with the cam.

[0012] By adopting the above technical solution, by setting a striking component, when the rotating shaft rotates, it will synchronously drive the cam to rotate. The smallest end of the cam's profile contacts and presses down on the movable plate, causing the movable plate to rotate around the connection point with the connecting plate as a fulcrum. This causes the other end of the movable plate to rise and compress the pressure spring. When the cam separates from the movable plate, gravity and the elasticity of the pressure spring can be used to strike the stone. Therefore, through the continuous rotation of the cam, the movable plate can periodically drive the striking rod to strike the stone, thereby facilitating the loosening of attached broken pellets and dust.

[0013] The invention is further configured such that: a sloping part is provided on the left side of the top of the movable plate, and the movable plate is used in conjunction with the cam through the sloping part; a movable shaft is provided inside the movable plate, and the movable shaft is connected to the side of the connecting plate near the connecting plate.

[0014] By adopting the above technical solution, the inclined surface can facilitate good contact between the cam and the movable plate, thereby facilitating the periodic movement of the movable plate. Furthermore, by setting a movable shaft, the movable plate and the connecting plate can be rotated together.

[0015] The present invention is further configured such that: the arc-shaped elastic sheet is semi-circular, and the side of the paddle away from the rotating roller is a smooth curved surface.

[0016] By adopting the above technical solution, by setting the arc-shaped elastic sheet in a semi-circular shape, the elasticity of the arc-shaped elastic sheet can be used to make a certain contact force between the paddle and the stone, thereby ensuring the positional stability of the brush bristles and the air blowing component, and making it easy for the stone to push the paddle to rotate, and to use the striking component to strike the stone.

[0017] The present invention is further configured such that: the guide bracket includes an upper fixed seat and a lower fixed seat, the upper fixed seat and the lower fixed seat are respectively connected to the side of the shot blasting chamber wall, a connecting seat is slidably arranged between the opposite sides of the upper fixed seat and the lower fixed seat, and guide rods pass through both sides inside the connecting seat, the side of the guide rod near the upper fixed seat and the lower fixed seat is respectively connected to both, a return spring is sleeved on the surface of the guide rod, and the side of the return spring near the upper fixed seat and the lower fixed seat is respectively connected to both, and mounting plates are welded to the opposite sides of the two connecting seats.

[0018] By adopting the above technical solution, and by setting up a guide bracket, when the lifting component rises, it will simultaneously drive the mounting plate and connecting seat to slide along the surface of the guide rod through the mounting bracket, and squeeze the return spring. The elasticity of the return spring can make a certain contact between the brush bristles and the stone, ensuring the cleaning effect of the brush bristles on the stone. Furthermore, it can make the brush bristles and the blower component adapt to the height of different stones, making the cleaning of shot and dust on the stone surface more flexible.

[0019] The present invention is further configured such that: the air blowing assembly includes an air blowing pipe, the air blowing pipe is rotatably connected to the bottom of the left mounting bracket, and the right side of the air blowing pipe is connected to a plurality of nozzles, the right side of the air blowing pipe is connected to a hollow shaft, the right side of the left mounting bracket is bolted to a housing, and the right side of the housing is rotatably connected to a drive gear, the front side of the hollow shaft extends into the interior of the housing, and a driven gear is sleeved on the surface of the hollow shaft, the drive gear meshing with the driven gear.

[0020] By adopting the above technical solution, the blowing component can be set up to drive the active gear to rotate through an external drive device. Through the meshing connection between the active gear and the driven gear, the driven gear and the hollow shaft can be rotated, which can change the spray angle of the nozzle, thereby flexibly utilizing and improving the blowing effect. Therefore, by using an external air generating device to deliver air through the hollow shaft to the inside of the blowing pipe, and then distributing it to multiple nozzles for spraying, the projectiles and dust can be further cleaned, improving the cleaning effect.

[0021] The present invention is further configured such that: a connecting sleeve is sleeved on the front side of the surface of the hollow shaft, and a sealing ring is provided on both the front and rear sides inside the connecting sleeve, and the surface of the sealing ring is in rotatable contact with the inner wall of the hollow shaft, and an air inlet pipe is connected to the top of the connecting sleeve.

[0022] By adopting the above technical solution, by setting a connecting sleeve and a sealing ring, external air source can be introduced into the connecting sleeve through the external air inlet pipe, and the sealing ring seals the connection sleeve and the hollow shaft, allowing air to enter the blower pipe through the hollow shaft and realize air flow.

[0023] The present invention is further configured such that: a connecting shaft is provided on both the front and rear sides of the roller, and the connecting shaft is connected to the side of the mounting plate closest to it.

[0024] By adopting the above technical solution, a connecting shaft can be set to enable the roller to rotate and the mounting plate to rotate, and external equipment can be connected to drive the roller to rotate, so that the stone can be cleaned by the rotation of the bristles.

[0025] A shot blasting process for roughening and anti-slip treatment of stone surfaces includes the following steps:

[0026] S1. Place the stone on the mesh belt conveyor structure, which will transport the stone to the shot blasting chamber. The shot blaster will spray the shot at high speed onto the surface of the stone to roughen it. The shot will fall into the separation structure, be sorted, and then be transported to the storage bin through the lifting structure. Finally, it will enter the shot blaster and be re-thrown.

[0027] S2. After the stone is roughened, there will be a few scattered pellets and dust impurities on the stone surface. When the stone passes through the lifting component, the lifting component will automatically raise the height of the roller and the air blowing component according to the height of the stone. It can adapt to stones of different heights. The conveying of the stone will drive the lifting component to rotate, which will knock on the stone, causing the dust and broken pellets attached to the stone to be loosened due to vibration.

[0028] S3. After being loosened, the fragmented shot and dust are swept away by brushes. At the same time, the dust and fragmented shot are blown onto the mesh belt conveyor structure and fall into the spiral shot collection structure, and then enter the separation structure for separation.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. By setting up a lifting component, when the roughened stone passes through the lifting component, the stone will push the lifting component to rise, which will then lift the roller and the air blowing component along the guide bracket. This allows the brush bristles and air blowing component to adapt to the height of the stone, thus providing flexibility for shot removal and dust removal. The conveying of the stone will drive the lifting component to rotate, causing the lifting component to periodically tap the stone. This vibration will loosen the broken shot and dust attached to the stone, thereby improving the cleaning effect of the subsequent brush bristles. Through the combined use of the air blowing component and brush bristles, the brush bristles pre-sweep the shot and dust on the stone, and then the air blowing component with an adjustable blowing angle blows the shot and dust away from the upper surface of the stone. The shot and dust fall into the spiral shot collection structure through the mesh belt conveyor structure, thereby playing a role in recycling residual shot and preventing dust pollution to the environment.

[0031] 2. By setting up a lifting component, when the roughened stone passes through the lifting component, the stone pushes the lifting component to rise, which in turn lifts the roller and the air blowing component along the guide bracket. This allows the brush bristles and air blowing component to adapt to the height of the stone, thus providing flexibility in shot removal and dust removal. The conveying of the stone drives the lifting component to rotate, causing the lifting component to periodically tap the stone. This vibration loosens the broken shot and dust adhering to the stone, thereby improving the cleaning effect of the brush bristles on the shot and dust. Through the combined use of the air blowing component and brush bristles, the brush bristles pre-sweep the shot and dust on the stone, and then the air blowing component with an adjustable blowing angle blows the shot and dust off the upper surface of the stone. The shot and dust fall through the mesh belt conveyor structure into the spiral shot collection structure, thus playing a role in recovering residual shot and preventing dust pollution.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1:

[0043] refer to Figure 1-7 A shot blasting device for roughening and anti-slip treatment of stone surface includes a mesh belt conveyor structure 1, a shot blasting chamber 19 bolted to the top of the mesh belt conveyor structure 1, and two shot blasters 9 bolted to the top of the shot blasting chamber 19. A separation structure 10 is bolted to the bottom of the mesh belt conveyor structure 1, and a lifting structure 11 is provided on the rear side of the separation structure 10. A storage bin 12 is provided on the top of the front side of the lifting structure 11, and the storage bin 12 is connected to the shot blasters 9. A spiral shot collecting structure 13 is bolted to the left side of the bottom of the mesh belt conveyor structure 1, and the spiral shot collecting structure 13 is connected to the separation structure 10. A shot removal structure 2 is provided on the left side inside the shot blasting chamber 19, and the shot removal structure 2 is used in conjunction with the mesh belt conveyor structure 1.

[0044] The shot blasting structure 2 includes two guide brackets 3, which are bolted to the left side inside the shot blasting chamber 19. Mounting brackets 4 are bolted to both sides of the opposite side of the two guide brackets 3. A blower assembly 5 is installed inside the left mounting bracket 4, and a lifting assembly 6 is bolted to the bottom of the right mounting bracket 4. A roller 7 is rotatably connected between the opposite sides of the two guide brackets 3, and the surface of the roller 7 is decorated with a ring of bristles 8. By using the lifting assembly 6, when the roughened stone passes through the lifting assembly 6, the stone pushes the lifting assembly 6 upwards, thereby lifting the roller 7 and the blower assembly 5 along the guide brackets 3 via the mounting brackets 4. This allows the bristles 8 and the blower assembly 5 to adapt to each other. The height of the stone allows for flexibility in shot removal and dust removal. The stone conveying process drives the lifting component 6 to rotate, causing it to periodically tap the stone. This vibration loosens the broken shot and dust adhering to the stone, improving the cleaning effect of the brush bristles 8. Through the combined use of the air blowing component 5 and the brush bristles 8, the brush bristles 8 pre-clean the shot and dust on the stone. Then, the air blowing component 5 with an adjustable blowing angle blows the shot and dust off the upper surface of the stone, which then falls through the mesh belt conveyor structure 1 into the spiral shot collection structure 13. This process helps to recover residual shot and prevent dust pollution.

[0045] like Figure 3 As shown, the lifting assembly 6 includes two fixed support plates 61, which are located at the bottom of the right-side mounting bracket 4. A rotating roller 62 is rotatably connected between the opposite sides of the two fixed support plates 61. A paddle plate 63 is annularly welded to the surface of the rotating roller 62. A rotating shaft 64 is bolted to both the front and rear sides of the rotating roller 62. The side of the rotating shaft 64 closest to the fixed plate 653 passes through the interior of the fixed plate 653 and is connected to a striking element 65. An arc-shaped elastic sheet 66 is welded to the top of both the fixed support plate 61 and the striking element 65. The top of the arc-shaped elastic sheet 66 is welded to the right-side mounting bracket 4. By setting up the lifting assembly 6, when the stone moves to the position of the paddle plate 63, it will push the paddle plate 63 and the rotating roller 62 to rotate. The other paddles 63 arranged around the rotating roller 62 come into contact with the upper surface of the stone, thereby raising the overall height of the rotating roller 62. This, in turn, raises the height of the roller 7 and the air blowing assembly 5 through the mounting bracket 4. Furthermore, the elasticity of the arc-shaped elastic sheet 66 allows the paddles 63 to adapt to the surface curvature of the stone, ensuring good contact between the paddles 63 and the stone. As the stone pushes the rotating roller 62 to rotate, it drives the striking element 65 to move through the rotating shaft 64. The striking element 65 periodically hammers the stone, causing it to vibrate. This loosens the broken pellets and dust adhering to the stone surface, thereby improving the cleaning effect of the subsequent brush bristles 8 and air blowing assembly 5.

[0046] like Figure 4As shown, the striking component 65 includes a connecting support plate 651, a rotating shaft 64 extending from the side near the connecting support plate 651 to the outside of the connecting support plate 651, and a cam 652 sleeved on the surface of the rotating shaft 64. Fixed plates 653 are welded to the top and bottom of the right side of the connecting support plate 651, and a connecting plate 654 is welded between the opposite sides of the two fixed plates 653. Movable plates 655 are rotatably connected to opposite sides of the two connecting plates 654 on the front and rear sides, and a striking rod 656 is welded to the right side of the bottom of the movable plate 655. A compression spring 657 is provided between the movable plate 655 and the top fixed plate 653. The movable plate 655 cooperates with the cam 652 to... The striking element 65 is provided. When the rotating shaft 64 rotates, it will synchronously drive the cam 652 to rotate. The smallest end of the cam 652 contacts the movable plate 655 and presses it down, causing the movable plate 655 to rotate around the connection point with the connecting plate 654. This causes the other end of the movable plate 655 to rise and compress the pressure spring 657. When the cam 652 separates from the movable plate 655, the striking rod 656 can strike the stone by using gravity and the elasticity of the pressure spring 657. Therefore, through the continuous rotation of the cam 652, the movable plate 655 can periodically drive the striking rod to strike the stone, thereby facilitating the loosening of attached broken pellets and dust.

[0047] like Figure 4 As shown, a sloping part 14 is provided on the left side of the top of the movable plate 655, and the movable plate 655 is used in conjunction with the cam 652 through the sloping part 14. A movable shaft 18 is provided inside the movable plate 655, and the movable shaft 18 is connected to the connecting plate 654 on the side close to it. By providing the sloping part 14, it is easy for the cam 652 and the movable plate 655 to have good contact, thereby facilitating the periodic movement of the movable plate 655. By providing the movable shaft 18, the movable plate 655 and the connecting plate 654 can be rotated.

[0048] like Figure 2 As shown, the arc-shaped elastic sheet 66 is semi-circular, and the side of the paddle 63 away from the rotating roller 62 is smooth curved. By setting the arc-shaped elastic sheet 66 to be semi-circular, the elasticity of the arc-shaped elastic sheet 66 can be used to make the paddle 63 have a certain contact force with the stone, thereby ensuring the positional stability of the brush bristles 8 and the air blowing component 5, and making it easy for the stone to push the paddle 63 to rotate, and to use the striking component 65 to strike the stone.

[0049] like Figure 6As shown, the guide bracket 3 includes an upper fixed seat 31 and a lower fixed seat 32. The upper fixed seat 31 and the lower fixed seat 32 are respectively connected to the inner wall of the shot blasting chamber 19 on their respective sides. A connecting seat 33 is slidably arranged between the opposite sides of the upper fixed seat 31 and the lower fixed seat 32. Guide rods 34 penetrate both sides of the connecting seat 33. The guide rods 34 are respectively connected to the upper fixed seat 31 and the lower fixed seat 32 on their respective sides. A return spring 35 is sleeved on the surface of the guide rod 34, and the return spring 35 is located near the upper fixed seat 31 and the lower fixed seat 32. One side is connected to both of them. The two connecting seats 33 are welded to the opposite side of each other with mounting plates 36. By setting the guide bracket 3, when the lifting component 6 rises, it will drive the mounting plate 36 and the connecting seat 33 to slide along the surface of the guide rod 34 through the mounting bracket 4, and squeeze the return spring 35. The elasticity of the return spring 35 can make the brush bristles 8 have a certain contact with the stone, ensuring the cleaning effect of the brush bristles 8 on the stone. It can also make the brush bristles 8 and the air blowing component 5 adapt to the height of different stones, making the cleaning of shot and dust on the stone surface more flexible.

[0050] like Figure 7 As shown, the air blower assembly 5 includes an air blower pipe 51, which is rotatably connected to the bottom of the left mounting bracket 4. Several nozzles 52 are connected to the right side of the air blower pipe 51, and a hollow shaft 53 is connected to the right side of the air blower pipe 51. A housing 54 is bolted to the right side of the left mounting bracket 4, and a drive gear 55 is rotatably connected to the right side inside the housing 54. The front of the hollow shaft 53 extends into the interior of the housing 54, and a driven gear 56 is sleeved on the surface of the hollow shaft 53. The drive gear 55 meshes with the driven gear 56. By setting up the air blowing component 5, the drive gear 55 can be driven to rotate by an external drive device. Through the meshing connection between the drive gear 55 and the driven gear 56, the driven gear 56 and the hollow shaft 53 can be rotated, which can change the blowing angle of the nozzle 52, thereby flexibly utilizing and improving the blowing effect. Therefore, by using an external air generating device to deliver air through the hollow shaft 53 to the inside of the air blowing pipe 51, and then distributing it to multiple nozzles 52 for spraying, further cleaning of projectiles and dust can be carried out, improving the cleaning effect.

[0051] like Figure 7 As shown, a connecting sleeve 15 is fitted onto the front side of the surface of the hollow shaft 53, and sealing rings 16 are provided on both the front and rear sides inside the connecting sleeve 15. The surface of the sealing ring 16 is in rotatable contact with the inner wall of the hollow shaft 53. An air inlet pipe is connected to the top of the connecting sleeve 15. By setting the connecting sleeve 15 and the sealing ring 16, external air source can enter the connecting sleeve 15 through the external air inlet pipe, and the sealing ring 16 seals the connection between the connecting sleeve 15 and the hollow shaft 53, allowing air to enter the blower pipe 51 through the hollow shaft 53, thus realizing air flow.

[0052] like Figure 5 As shown, the front and rear sides of the roller 7 are provided with connecting shafts 17, and the side of the connecting shaft 17 close to the mounting plate 36 is connected to it. By setting the connecting shaft 17, the roller 7 can be rotatably connected to the mounting plate 36, and it is convenient for external equipment to drive the roller 7 to rotate, and the stone is cleaned by the rotation of the brush bristles 8.

[0053] Brief description of the process: The stone is placed on the mesh belt conveyor structure 1, which transports it to the shot blasting chamber 19. Shot blasters 9 propel high-speed shot onto the surface of the stone, roughening it. The ejected shot falls into the separation structure 10, is sorted, and then transported to the storage silo 12 via the lifting structure 11. Finally, it enters the shot blaster 9 again, where the shot is re-ejected. When the stone moves to the position of the paddle 63, it pushes the paddle 63 and the rotating roller 62 to rotate, causing the other paddles 63 surrounding the rotating roller 62 to interact with the upper surface of the stone. The surface contact causes the overall height of the roller 62 to rise, which in turn pushes the connecting seat 33 to slide on the surface of the guide rod 34 via the mounting bracket 4, thus raising the roller 7 and the air blowing assembly 5. Furthermore, utilizing the elasticity of the arc-shaped elastic sheet 66, the paddle 63 can adapt to the surface curvature of the stone, ensuring good contact between the paddle 63 and the stone. As the stone pushes the roller 62 to rotate, it drives the cam 652 to rotate via the rotating shaft 64. The smallest end of the cam 652 contacts and presses down on the movable plate 655, causing the movable plate 655 to... The connection point of the connecting plate 654 is a fulcrum for rotation, causing the other end of the movable plate 655 to rise and compress the pressure spring 657. When the cam 652 separates from the movable plate 655, gravity and the elasticity of the pressure spring 657 allow the striking rod 656 to strike the stone. Therefore, through the continuous rotation of the cam 652, the movable plate 655 can periodically drive the striking rod to strike the stone, causing the stone to vibrate. This loosens the broken shot and dust adhering to the stone surface. Finally, the external drive device drives the roller 7 and the brush. The rotating blade 8 cleans the stone, and then drives the drive gear 55 to rotate through an external drive device. The drive gear 55 and the driven gear 56 mesh together, which drives the driven gear 56 and the hollow shaft 53 to rotate. This changes the spray angle of the nozzle 52. Therefore, the external air generating device delivers air through the hollow shaft 53 to the inside of the air blowing pipe 51, which is then distributed to multiple nozzles 52 for further cleaning of the shot and dust. The residual shot enters the spiral shot collection structure 13 and then enters the separation structure 10 for recycling.

[0054] Example 2:

[0055] like Figure 8 As shown, the present invention also provides a shot blasting process for roughening and anti-slip treatment of stone surfaces, comprising the following steps:

[0056] S1. Place the stone on the mesh belt conveyor structure 1, and the mesh belt conveyor structure 1 will transport the stone to the shot blasting chamber 19. The shot blaster 9 will spray the shot at high speed onto the surface of the stone to roughen the stone. The shot that is thrown out falls into the separation structure 10 and is sorted. Then it is transported to the storage bin 12 through the lifting structure 11 and finally enters the shot blaster 9 to be thrown out again.

[0057] S2. After the stone is roughened, there will be a few scattered pellets and dust impurities on the surface of the stone. When the stone passes through the lifting component 6, the lifting component 6 will automatically raise the height of the roller 7 and the air blowing component 5 according to the height of the stone. It can adapt to stones of different heights. The conveying of the stone will drive the lifting component 6 to rotate, which will knock on the stone, causing the dust and broken pellets attached to the stone to be loosened due to vibration.

[0058] S3. After being loosened, the broken pellets and dust are swept away by the brush bristles 8. At the same time, the dust and broken pellets are blown onto the mesh belt conveyor structure by the air blowing component 5 and fall into the spiral pellet collecting structure 13, and then enter the separation structure 10 for separation.

[0059] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
